BEST AVMLABLE CO? formed as a may be separate member, and is at tached to the spring plank directly. In the forms illustrated in Figs. 3 and 4, the upper guard members are adapted to be employed either in conjunction with the third or fourth point supportingr arrangement above described, or independently thereof, it being understood that a fourth point guide member maybe carried ony the supporting member in coperation with a fourth point supporting shoe carried on the tension member of the brake beam,l or the guide member omitted or supplied in the form of an overhung support, the supporting member.7 being utilized to form a lower safety guard. If desired, the upper guard member l0 insuch arrangements as those illustrateu may be made of spring ,metal and disposed so that-'the brake beam will make contact therewith just prior to the limit-of the braking movement of the beam, so that said spring member will be placed under tension when the brakes are applied. Then, uponV4 release of the brakes, the reaction of the' spring mem r. will assist in the throw-olf,` so4 as to completely remove the brake slices from contact with the wheels.

From the foregoing description of my in- Y vention, it will be seen that it provides a very simple and economical guard member which may be incorporated in a variety of conventional truck structures in conjunction with various well known forms of equipment, and that it will coperate with various portions thereof, such as the lower safety support, to contribute materially to the sta- `member supported bility, effectiveness and safety of the brake gear.

While I have shown a variety of forms in which the invention may be embodied, I am aware that itis susceptible of still further modification and variation, and that it is not limited to use in conjunction with the illustrative form of brake beam herein shown. Accordingly, it is my intention that the appended claims comprehend all structural modifications and arrangements within the proper scope of the invention.

at I claim is:

1. In a brake rigging including a brake beam, a Arigid safety bar member, and a yielding resilient member secured thereto and arranged under the beam, said yielding` resilient member being designed to guide the beam in its movement, and an upper guard member arranged above a part of the beam to prevent undue excess vertical moir'ement of the beam. v

2. In a truck rigging including a brake beam and a spring plank disposed in association therewith, a resilient upper guard by the spring plank -in position to limit upward movement of the beam and to be placed under tension upon braking movement of the same. l

In testimony whereof I hereunto afix my signature this 20th day of June, 1917.
